Be it known that I, GAYLE L. SQL-'Inn a citizen the United States, residing` at lvlastings, in the county of St. Johns and f te of Florida, have invented a nev.7

and useful Ladder of which the following is specification.

rlhis invention relates to ladders, and `yiore particularly to folding ladders.

The object ofthe invention is to provide a ladder of this character constructed to be used as a straight ladder, as a step ladder, or as a trestle andivhich when folded, can be stored in a small space. p

Another objectA of the invention is to provide a folding` ladder, the sections of Which are hingedly connected and equipped with slidable locls to hold the sections rigid When in longitudinal alineinent 'and shiftable to permit them to `fold for use as a step ladder or to be collapsed for storage.

W ith the foregoing` and other objects in view which will appear as the description proceeds, the invention resides in the cornbination and arrangement of parts and in the details of construction hereinafter described anc claimed, itv being` understood' that changes in the precise embodiment of .the invention herein disclosed may be made vwithin the scope of what is claimed Without departingfrom the spirit of the invention.

In the accompanying drawings Figure l represents a side elevation of the ladder constituting this. invention shown in positionfor use as a step ladder.

Fig. Q, is a front elevation thereof. Y

Fig. 3 is a longitudinal section taken on the line 3h23 of Fig. 2.

F ig. d is a detail side elevation of the ladder with the sections extended and looked in longitudinal alinement, and

F 5 is a detail transverse section taken on the line 5-5 of Fig. d.

In the embodiment illustrated, the ladder constituting this invention is composed of two sections l and 2, the side bars 3 of which are hingedly connected at their inner ends as shown at et. The hinged ends of these sections are equipped With slidable locks 5 which are constructed exactly alike and hence one only Will be described in detail.

These locks each comprises a plate 6 countersunk in one side face of one of the section bars and` secured thereto by any suitable means. A stud or stud shaft 7 proll and e. rlfhe lug l at t ljects laterally onward from the outer face of this plate and is d C1Aied to pass throu a slot ll in a casn l0 which con. 'itu the sliding member o" he lool.: and which s therewith ned to oveL i l eer sections shown elcarlj.' in the inner cui, f le castingl has an inturued liaujre ld f" engage the inner face of the s. .fhich it operates. This casting; provided at its inner end With an aper 'ifV designed to When the sections and Q are in opened straight out position with a cooperating aperture 1G formed in the adjacent ladder section so that when the sliding casting; l0 is moved to bridge the joint between the sections, theaperture l5 therein Will register with the aperture i6 to receive a securing` pin 7 7 carried by a chain 18 attached at one end to the section l.

lt Will thus be seen that When these lock` ing,- castings l() are shifted to bridge the joints between the sections and are secured i l f ecured in sliding` engagement Vby the pins 17, the sections 'Will be rigidly held against foldingl to adapty the ladder for use a straight ladder.

When the .ladder is to be used as a step ladder, or to be folded for storage` the slid*- ing castings l0 are shifted longitudinally into the position shoivn in l., 2 and 3, it of course beingunderstood that the pins 17 are first Withdrawn. lWhen these caste ings are so shifted, the sections l and 2 may be swung` on their hinges and when desired for use as a step ladder are secured in substantially Asshaped form by means of brace rods 19 which are pivotally connected at one end to the side bars of one section and provided at their free ends with hooks as 20 adapted to be engagedivith keepers 2l carried by the opposed sections so that the sections ivill be securely held in the position shown in F l for use as a step ladder.

Spring clips 22 are mounted on the inner faces of the side bars to 1ivhich 'the rods 19 are secured, and are designed to yieldably hold said rods when not in use to prevent thein swinging and dangling around, as is shown clearly in Fig. 3.

The side bars of section 1 are provided on into the position shown .in Fig. Ll, the pin 17 will pass through the end Vot the casting, througrn the side har oit the ladder section 'i' l .1 v l l Y1 1 and through the lia-nge 11, ano. thus securely lock the sections against separa-ting as well 'as against folding movement.

Frein the above description it will he obvious that this ladder may he quickly set up 'for use as an extension or straight ladder by shifting the castings 10 in the Inanner above described, or it may be folded t'or use as a step ladder opening' up the sections and securing them by the brace hars 19 and when desired to fold the ladder tor storage, the brace bars'19 are disengaged from the keepers 21 and swung; into the position shown in Fig. 3, beingheld by the clips The snap hooks 23 are then engagged With the eyes of keepers 21 and hold the sections in folded position ready for storage.

of one section and fixed thereto, a stud pro-v jecting laterally fromV said plate, a longitudinally slotted casting` slidahle on said plate with said pin projecting through said slot Vand having lateral lugsv to oi'erlie the edge oit the bar on which the casting is mounted, said Vcasting` having an aperture and one o'if said lugs having' an inturned flange apertured to register with the aperture in the casting, the other ladder section having' an aperture to register with said casting apertures when the castingv is moved to bridge the joint between the sections, and a pin to enter said registerinfg,- apertures to lock the sections in open position.

In testimony that I claini the foregoing rny own, l have heretoV atlixed my signature in the presence of two Witnesses.
